This document is an engineering report describing a 5 V / 3.0 A or 9 V / 3 A output USB Type-C with support of USB PD 3.0 and PPS protocol using the InnoSwitch3-CP INN3266C-H210 IC and Weltrend WT6615F USB Type-C USB PD controller. This design shows the high power density and efficiency that is possible due to the high level of integration of the InnoSwitch3-CP controller providing exceptional performance. This document contains the power supply specification, schematic, bill of materials, transformer documentation, printed circuit layout, and performance data.


  • USB PD 3.0 with PPS support via single secondary-side IC (CCG3PA CYPD3175)
  • InnoSwitch3-CP is the industry’s first AC/DC IC with isolated, safety rated integrated feedback
  • All the benefits of secondary-side control with the simplicity of primary-side regulation
  • Insensitive to transformer variation
  • Built-in synchronous rectification for high efficiency
  • Meets DOE6 and CoC V5 2016 efficiency requirement (>1 % efficiency margin)
  • Micro stepping of voltages and CC thresholds in compliance with PPS protocol
  • Output overvoltage and overcurrent protection
  • <30 mW no-load input power
  • Integrated thermal protection
